Validation

This is the official documentation of the agent_ruby Ruby agent.

A field failing validation

• Columns of type VARCHAR(15) will automatically carry a less than 15 chars validator.

• Non-nullable columns will automatically carry a Present validator.

However, you may want to enforce stricter restrictions than the ones which are implemented in your data source.

Adding validation rules

The list of operators (Present, LongerThan, ...) which can be used when adding validators is the same as the filter operators.

include ForestAdminDatasourceToolkit::Components::Query::ConditionTree

@create_agent.customize_collection('customer') do |collection|
  collection.add_field_validation('firstName', Operators::PRESENT)
    .add_field_validation('firstName', Operators::LONGER_THAN, 2)
    .add_field_validation('firstName', Operators::SHORTER_THAN, 13)
    .add_field_validation('firstName', Operators::MATCH, /^[a-z]+$/)
end
